To Study the Functional Outcomes of Proximal Fibular Osteotomy in Osteoarthritis Kee

ABSTRACT

Introduction: Knee osteoarthritis (OA), also known asdegenerative joint disease, is typically the result of wearand tear and progressive loss of articular cartilage leadingto radiologically decreased joint space. Proximal fibularosteotomy (PFO) is an alternative treatment to high tibialosteotomy (HTO). Hence; under the light of above mentioneddata, the present study was undertaken for assessing thefunctional outcomes of proximal fibular osteotomy inosteoarthritis knee.Material and methods: A total of 10 patients with OA ofknee were enrolled in the present study. The patients wereplaced in the supine position after administration of spinalanaesthesia. An approximately 5-cm longitudinal incisionwas made over the lateral aspect of the proximal fibula, andthe fibula exposed between the peroneus muscle and soleusmuscle. PFO was performed under the hands of skilled andexperienced orthopaedic surgeon. Knee pain was assessedusing a Visual analogue scale. Knee ambulation activitieswere recorded using the knee and function subscores of theAmerican Knee Society score (KSS). All the results wererecorded in Microsoft excel sheet and were analyzed by SPSSsoftware. Chi- square test and Mann Whitney U test were usedfor assessment of level of significance.Results: Mean KSS score at pre-operative, postoperative,postoperative 6 weeks and postoperative 9 months werefound to be 44.03, 53.50, 58.60 and 68.14 respectively.Significant results were obtained while comparing the meanKSS at different postoperative time intervals. In the presentstudy, mean VAS score at pre-operative, postoperative,postoperative 6 weeks and postoperative 9 months were foundto be 8.77, 6.96, 4.36 and 2.52 respectively. Significant resultswere obtained while comparing the mean VAS at differentpostoperative time intervals.Conclusion: PFO is a novel alternative method in themanagement of medial compartment arthritis of the knee.
